Oxalate oxidase catalyzes the oxidation of oxalate, converting it into carbon dioxide and hydrogen peroxide. Traditionally considered a metabolic end-product, oxalate can participate in metabolic regulation. Widely distributed in plants, the enzyme’s activity is particularly notable in seeds and during germination, where it is linked to developmental processes and cell wall modification. The enzymatic product hydrogen peroxide serves multiple roles: At low concentrations, it acts as a signaling molecule, functioning as a second messenger in various cellular pathways; At higher concentrations, it facilitates the cross-linking of cell wall polymers, critical for cell wall strengthening, lignification, and defense responses. AkrivisBio’s Oxalate Oxidase Activity Assay is a simple, sensitive way to measure enzyme activity in a variety of sample types.
